My Safe-T-Alert combo CO/Propane detector is rated at 108 mA nominal current draw. So at that rate it will draw around 2.6 AH/day or 36 AH in 2 weeks.

Electronic devices are typically rated at peak power which for an alarm means with the alarm sounding. Operating currents without the alarm sounding are more likely to be 0.0l - 0.02 amp. Here is an example with a typical "supply current" of 17 mA, equals 0.017 A. That is equivalent to 12 AH/month. Many batteries can lose more than that with no draw.
